The residual effects of a blowjob still remaining upon a womans lips in the immediate hours after said blowjob.
So your friend got a blowjob on the way to meet you, and you know this. And when she goes to kiss you on the cheek after dinner you step back quickly because you dont want any of your friends second hand semen from her lips, and or mouth to reach any portion of your skin.

This happens to Larry David in season 7, episode 2 of Curb Your Enthusiasm.

Get the Second Hand Semen mug.
One's hand after one finishes jacking off.
President Trump jacked off before he gave the State of the Union Address. During his speech Trump was making a lot of hand gestures. Semen was flying all over 'cause Trump did not wash up after spanking the monkey. The Pres had a clear case of semen hand.
